Bombardier 4.8
The Bombardier 4.8 is a Canadian sailing dinghy that was designed by Bombardier Research as a day sailer and first built in 1982.Sherwood, Richard M.: ''A Field Guide to Sailboats of North America, Second Edition'', pages 62-63. Houghton Mifflin Company, 1994. Production The design was built by Bombardier Limited in Canada, but it is now out of production. Design The Bombardier 4.8 is a recreational sailboat, built predominantly of fibreglass, with polyurethane flotation and aluminum spars. It has a fractional sloop rig, a raked stem, a vertical transom, a flip-up, transom-hung rudder controlled by a tiller and a flip-up centreboard keel. It displaces and can accommodate four people. The design features an adjustable outhaul, boom vang, Cunningham and a roller furling genoa. It is also fitted with adjustable hiking straps. There is a small stowage compartment in the bow. The design employs a vacuum cockpit self-bailer that can be left open when the boat is stationary. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bombardier Inc
Bombardier Inc. () is a Canadian business jet manufacturer. It was also formerly a manufacturer of commercial jets, public transport vehicles, trains, and recreational vehicles, with the last being spun-off as Bombardier Recreational Products. The company originally produced Ski-doo snowmobiles, over time expanding into the aviation, light and heavy rail, and public transit businesses. Bombardier manufactures several series of corporate jets, Global 7500, Global Express, Challenger 650 and Challenger 3500. History Bombardier Recreational Products In January 1934, a blizzard prevented Joseph-Armand Bombardier from reaching the nearest hospital in time to save his two-year-old son, Yvon, who died from appendicitis complicated by peritonitis. Bombardier was a mechanic who dreamed of building a vehicle that could "float on snow". In 1935, in a repair shop in Valcourt, Quebec, he designed and produced the first snowmobile using a drive system he developed that revolutio ...

Raked Stem
The stem is the most forward part of a boat or ship's bow and is an extension of the keel itself. It is often found on wooden boats or ships, but not exclusively. Description The stem is the curved edge stretching from the keel below, up to the gunwale of the boat. It is part of the physical structure of a wooden boat or ship that gives it strength at the critical section of the structure, bringing together the port and starboard side planks of the hull. Plumb and raked stem There are two styles of stems: ''plumb'' and ''raked''. When the stem comes up from the water, if it is perpendicular to the waterline it is "plumb". If it is inclined at an angle to the waterline it is "raked". (For example, "The hull is single decked and characterized by a plumb stem, full bows, straight keel, moderate deadrise, and an easy turn of bilge.") Stemhead Because the stem is very sturdy, the top end of it may have something attached, either ornamental or functional in nature. On small ...

Spinnaker
A spinnaker is a sail designed specifically for sailing off the wind on courses between a reach (wind at 90° to the course) to downwind (course in the same direction as the wind). Spinnakers are constructed of lightweight fabric, usually nylon, and are often brightly colored. They may be designed to perform best as either a reaching or a running spinnaker, by the shaping of the panels and seams. They are attached at only three points and said to be ''flown''. Nomenclature Informal names for a spinnaker are ''kite'' or ''chute'' (owing to their resemblance to a parachute in both construction and appearance). Boats may have more than one spinnaker, differentiated by a letter to indicate symmetric (S) or asymmetric (A) and a number to indicate size (with higher numbers indicating smaller size), e.g. ''A1'' would be a large asymmetric sail and ''S3'' would be a smaller symmetric sail. Operation A spinnaker is used for sailing with the direction of the wind. Symmetrical ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trailer (vehicle)
A trailer is an unpowered vehicle towed by a powered vehicle. It is commonly used for the transport of goods and materials. Sometimes recreational vehicles, travel trailers, or mobile homes with limited living facilities where people can camp or stay have been referred to as trailers. In earlier days, many such vehicles were towable trailers. United States In the United States, the term is sometimes used interchangeably with travel trailer and mobile home, varieties of trailers and manufactured housing designed for human habitation. Their origins lay in utility trailers built in a similar fashion to horse-drawn wagons. A trailer park is an area where mobile homes are placed for habitation. In the United States trailers ranging in size from single-axle dollies to 6-axle, high, long semi-trailers are commonplace. The latter, when towed as part of a tractor-trailer or "18-wheeler", carries a large percentage of the freight that travels over land in North America. Types ...

Beaching (nautical)
Beaching (or Landing) is the process in which a ship or boat is laid ashore, or grounded deliberately in shallow water. This is more usual with small flat-bottomed boats. Larger ships may be beached deliberately; for instance, in an emergency, a damaged ship might be beached to prevent it from sinking in deep water. Some vessels are designed to be loaded and unloaded by beaching; vessels of this type used by the military to disembark troops under fire are called landing craft. During the age of sail, vessels were sometimes beached to allow them to be rolled over for the hull to be maintained, a process called ''careening''. Ships scheduled for break-up are sometimes intentionally beached to make the procedure easier. See also * Landing craft * Shipwrecking * Cetacean stranding Cetacean stranding, commonly known as beaching, is a phenomenon in which whales and dolphins strand themselves on land, usually on a beach. Beached whales often die due to dehydration, collapsing under t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hand Bailer
Bailing is the process of removing water from a vessel. Hand bailers A hand bailer is a device used for manually removing water which has entered a vessel. In the simplest case, it is merely a smaller container which can be filled and then emptied. This kind of device has been in use since early times. It is still in use on small boats and rafts, though some are ''self-bailing''. Some regulations require either or both forms of bailing.ISAF (International Sailing Federation), liferafts File:Nydam.5.jpg, Iron Age hand bailer from Nydam Mose File:Auskjer.JPG, Norwegian "auskjer", traditional hand bailer File:RK 1701 1154 Ösfass.jpg, modern plastic hand bailer Self bailers For some modern types of dinghys in sailing sports hand bailers can be obsolete when they are equipped with self bailers, sometimes also called automatic bailers. Self-bailing boats are shaped so that they will drain completely if filled with water; powered by the venturi effect and the motion of the boat, ...

Hiking Strap
In sailing, hiking (stacking or stacking out in New Zealand; leaning out or sitting out in United Kingdom) is the action of moving the crew's body weight as far to windward (upwind) as possible, in order to decrease the extent the boat heels (leans away from the wind). By moving the crew's weight to windward, the moment of that force around the boat's center of buoyancy is increased. This opposes the heeling movement of the wind pushing sideways against the boat's sails. It is usually done by leaning over the edge of the boat as it heels. Some boats are fitted with equipment such as hiking straps (or toe straps) and trapezes to make hiking more effective. Hiking is most integral to catamaran and dinghy sailing, where the lightweight boat can be easily capsized or turtled by the wind unless the sailor counteracts the wind's pressure by hiking, or eases the sails to reduce it. The heavy keel on larger keelboats means that it is rare to capsize them due to wind alone, but keelboa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genoa (sail)
A genoa sail is a type of large jib or staysail that extends past the mast and so overlaps the main sail when viewed from the side, sometimes eliminating it. It was originally called an "overlapping jib" and later a genoa jib. It is used on single-masted sloops and twin-masted boats such as yawls and ketches. Its larger surface area increases the speed of the craft in light to moderate winds; in high wind, a smaller jib is usually substituted, and downwind a spinnaker may be used. Definition The term ''jib'' is the generic term for any of an assortment of ''headsails''. The term ''genoa'' (or genny) refers to a type of jib that is larger than the 100% foretriangle, which is the triangular area formed by the point at which the stay intersects the mast, and deck or bowsprit, and the line where the mast intersects deck at the rail. Colloquially the term is sometimes used interchangeably with ''jib''. A working jib is no larger than the 100% foretriangle. A genoa is larger, with ...

Roller Furling
Roller furling is a method of furling (i.e. reefing) a yacht's staysail by rolling the sail around a stay. Roller furling is typically used for foresails such as jibs or genoas. A mainsail may also be furled by a similar system, whereby the sail is furled within the mast or around a rotating boom (or around a rotating shaft within a boom). Although staysail roller-furling is effective and very common, in-mast or in-boom mainsail furling involves some compromises, and mainsail slab reefing gives a better sail shape. Methods The idea for a furling jib is usually attributed to Major E du Boulay in England who invented a device similar to a roller blind for reefing a jib. Major Wykeham-Martin used one of Boulay's rollers and improved the system by incorporating roller bearings in 1907 when the system was patented. The original castings were made by London-based toilet makers Bouldings. By the 1940s nearly every British cruising yacht was fitted with this furling system. An early v ...

Cunningham (sailing)
In sailing, a cunningham or cunningham's eye is a type of downhaul used on a Bermuda rigged sailboat to change the shape of a sail. It is named after its inventor, Briggs Cunningham, a victorious America's Cup skipper and yacht builder. The cunningham differs from a typical downhaul in the way that it attaches to the sail. The system usually consists of a line which is secured at one end to the mast or boom below the foot of the mainsail. It is then passed through a cringle in the luff of the sail near the foot, but above the tack, and then led down on the other side to a fitting on the mast or boom or on deck. The tension in the luff of the sail is adjusted using a combination of the halyard and the cunningham (where fitted). The primary advantage of adjusting the cunningham is the speed and ease with which the luff tension can be changed while sailing or racing. By either hauling or easing the line, the tension in the luff can be changed, thereby shifting the point of ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boom Vang
A boom vang (US) or kicking strap (UK) (often shortened to "vang" or "kicker") is a line or piston system on a sailboat used to exert downward force on the boom and thus control the shape of the sail. The Collins English Dictionary defines it as "A rope or tackle extended from the boom of a fore-and-aft mainsail to a deck fitting of a vessel when running, in order to keep the boom from riding up". The vang typically runs from the base of the mast to the boom. Due to the great force necessary to change the height of the boom while a boat is under sail, a line-based boom vang usually includes some sort of a pulley system. Hydraulic piston vangs are used on larger sailboats and controlled by manual or electric hydraulic pumps. By controlling leech tension, the boom vang is one way of controlling sail twist. The boom vang may also be used to flatten the mainsail on dinghies. On small sailboats and some cruising sailboats a vang may be omitted. If a vang is not installed, then th ...
